Fig. 1-2 show a waterproof structure for assembling a connector disclosed in this embodiment, which mainly includes a housing 10, a fixing plate 40, a threaded sleeve 30 and a connector 50. The connector 50 is a standard external female connector commonly available in the market, and includes a socket section, a threaded section, a flange section and a core line section which are connected in sequence. The shell 10 is provided with a first through hole, the fixing plate 40 is provided with a second through hole, the core wire section is positioned below the fixing plate 40, the flange section is abutted against the bottom of the fixing plate 40, the socket section and the thread section penetrate through the second through hole and are positioned above the fixing plate 40, and the socket section is positioned in the first through hole. The threaded sleeve 30 is in threaded connection with the threaded section, two ends of the threaded sleeve 30 are respectively abutted to the bottom of the shell 10 and the top of the fixing plate 40, an annular groove is formed in a connecting gap between the threaded sleeve 30 and the shell 10, the annular groove surrounds the periphery of the socket section, and a waterproof structure is arranged in the annular groove.

In the specific implementation process, the section of the annular groove is triangular, rectangular or semicircular, an annular first flaring structure 11 is arranged at the bottom of the shell 10 corresponding to the position around the first through hole, an annular second flaring structure 31 is arranged at the top of the screw sleeve 30 corresponding to the position around the screw hole, and the annular groove is surrounded by the first flaring structure 11 and the second flaring structure 31. In this embodiment, the cross section of the annular groove is a triangular structure, that is, the first flaring structure 11 is an annular inclined wall structure disposed at the bottom of the outer shell 10 corresponding to the surrounding position of the first through hole, and the second flaring structure 31 is an annular inclined wall structure disposed at the top of the screw sleeve 30 corresponding to the surrounding position of the screw hole, that is, as shown in fig. 1.

In this embodiment, the waterproof structure is a waterproof rubber ring 20 made of rubber or silica gel with certain elasticity. By sizing, the threaded section of the connector 50 is first screwed onto the fastening plate 40 by the threaded sleeve 32 of the threaded sleeve 30. Then the waterproof rubber ring 20 is placed on the second flaring structure 31 of the end face of the screw sleeve 30, finally the waterproof rubber ring 20 is pressed through the shell 10, and the shell 10 is matched with the screw sleeve 30 and the connector 50. The inclined wall surface (namely the first flaring structure 11) of the waterproof rubber ring 20 on the threaded sleeve 30 and the inclined wall surface (namely the second flaring structure 31) on the shell 10 are jointly acted to extrude the connector side wall 51, and the waterproof rubber ring 20 is made of rubber or silica gel and has certain deformability and elasticity, so that the waterproof rubber ring 20 can deform to be in close contact with and matched with each other. Therefore, external fluid cannot enter the interior from the gap between the shell 10 and the threaded sleeve 30 or enter the interior from the gap between the connector 50 and the threaded sleeve 30, so that the waterproof effect is achieved, and internal electronic components are protected from being damaged by fluid short circuit such as internal water inlet.

It should be noted that, in consideration of practical requirements of the structural scheme, the top end of the connector 50 cannot exceed the surface of the housing 10, that is, the top end of the socket section is flush with the upper surface of the housing 10, or the top end of the socket section is lower than the upper surface of the housing 10.

Referring to fig. 3, the present embodiment further discloses a waterproof programmable controller, which has a plurality of the above-mentioned connector-equipped waterproof structures, wherein the housing 10 of each connector-equipped waterproof structure shares the housing of the waterproof programmable controller, and the fixing plate 40 of each connector-equipped waterproof structure is integrally formed and located inside the waterproof programmable controller. As for the waterproof programming controller, other circuit structures are the same as those of the conventional programming controller on the market, and therefore, the description thereof is omitted in this embodiment. This programming controller who contains connector waterproof construction, because of actual overall dimension demand connector 50 can not the protrusion be high and cross the casing surface, nevertheless the equipment is whole to have waterproof demand, therefore 12 connectors 50 in top are inside all to have adopted this connector waterproof construction, fine solution the product waterproof demand.

The above only be the preferred embodiment of the utility model discloses a not consequently restriction the utility model discloses a patent range, all are in the utility model discloses a conceive, utilize the equivalent structure transform of what the content was done in the description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection within range.
